Power System Challenges in Modern Electronics
Engineers face growing demands for power stability as industrial systems and EVs push voltage requirements beyond 100V. Ripple current handling and thermal performance become critical pain points where conventional capacitors fail under stress.
BHC AL30A472NJ400N Technical Breakthroughs
- 4700µF capacitance (±20%) ensures stable voltage delivery during load fluctuations (KEMET DS-10231)
- 400V rating withstands automotive cold-crank scenarios (AEC-Q200 qualified)
- Low ESR (18mΩ @ 100kHz) reduces power losses by 23% (Third-party lab test#CTL-224)
- 125°C operational range enables deployment near power semiconductors
